At a New York Fashion Week party earlier this week, Lancôme ambassador Taylor Hill modelled a pretty spectacular use of purple eyeliner - along her lower inner rim. It was visible enough to pick up on the violet hues in her dress, looked very flattering against her green eyes, and was just about the best example of how to experiment with colour if you're at all hesitant.

If you want to try this at home, just follow what Hill did - use black liner up top, dust on neutral eyeshadow and load up on mascara.
